Weyl almost periodic solutions to abstract linear and semilinear equations with Weyl almost periodic coefficients

摘要

> In this work, we study the existence and uniqueness of bounded Weyl almost periodic solution to the abstract differential equation u ′ ( t )? = ? A u ( t )?+? f ( t ), t ∈ R , in a Banach space X , where A : D A ? X → X is a linear operator (unbounded) that generates an e
